How to Remove Liquid Nails from Drywall
Liquid nails are a type of construction adhesive often used to attach trim, panels, or other materials to walls. While liquid nails provide a strong bond, they can be difficult to remove fully once dried.
Removing liquid nails from drywall takes some work, but it can be done with the right techniques and tools.
Step 1: Apply Heat
Heat is very effective for softening cured liquid nails. Use a heat gun or blow dryer to heat the adhesive. Move the heat continuously over the drywall until the adhesive softens and becomes pliable.
Be careful not to overheat the area as too much heat can damage the drywall’s paper face.
Step 2: Scrape Away Adhesive
Once heated and softened, use a putty knife to scrape and pry away the liquid nails from the drywall. You may need to reheat the adhesive multiple times as you work to fully remove it.
Scrape slowly and carefully to avoid damaging the wall underneath. A plastic putty knife is preferable to metal for drywall as it reduces scratching.
An electric heat gun on a low setting is ideal for softening the adhesive while minimizing the risk of damage to the wall.
Step 3: Use Mineral Spirits To Clean
Once you’ve removed the main adhesive from drywall, wet a rag with mineral spirits to wipe away any remaining residue. Mineral spirits help dissolve and clean off the stubborn leftover adhesive.
Be sure to use mineral spirits in a well-ventilated area and avoid any open flames, as it’s flammable.
You may need to apply a bit of petroleum jelly to remove dried adhesive in textured areas. Gently rub it in and then wipe it off along with the adhesive.
Step 4: Sand and Skim Coat if Needed
If any gouges remain after liquid nail removal, fill them with joint compound. Once dry, sand smooth and use a wide drywall knife to skim coat the area to blend it with the surrounding wall.
Prime and paint once finished for an even repair.
- Try applying baby oil or WD-40 to help soften old liquid nails and make it easier to scrape off.
- For stubborn dried adhesive, reapply heat and let it sit for 5-10 minutes to fully penetrate before scraping.
- Avoid using sharp metal scrapers which can cut into the paper exterior of drywall.
- Work slowly and carefully to avoid damaging the wall surface.
- Wear safety glasses and chemical-resistant gloves when using mineral spirits.
With some perseverance and the right techniques, you can successfully remove pesky liquid nails from drywall without damage.
Just take your time and be cautious when applying heat and scraping. In no time, you’ll have a smooth, clean wall ready for your next project.
